A game jam theme is not meant to restrict you to a very specific kind of game. You are free to interpret the theme in whichever way you want, and the judges/players will then rate the way you incorporated the theme by how unique or how fun it was and any other criteria.
There are many different types of themes you could get in game jams. I would say this one is on the more restrictive side in my opinion though, but there's still plenty of things you could think of!
